I had to mess with the gamma and gain in order to make the blue drill tents more visible.

Even then, I can only see 5. There’s a 6th one somewhere else in Colina west and a 7th doing in fill somewhere on Colina. Having just finished monsoon season, the area (as you can see) is super green. But by May/June the land in that area starts browning and looking pretty dry and arid.

The next sentinel image should be available by this weekend. Hopefully it’s cloudless and we can see where the next holes are being done (might give us a clue if those southern most holes are finding anything)
